Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

AB Feature Request - Ability to move AU midi FX from FX slot
Some plugins, such as Atom piano roll can go in a midi FX slot or in an input slot. If placed in the input slot, they can be placed into an additional lane. If put in the FX slot, they can’t be reused.
Sometimes it makes sense to have such a plugin in the FX slot, for instance to take advantage of an input app such as Xequence Keys, or to record output from Rozeta. But then, moving that to a new lane isn’t possible. In this case you need to save a preset in the app, open a new instance, then load the preset. (Possible only in the Beta at this time...)
Low priority, since there’s a workaround (at least in the beta) but still would be nice.
